' GOLF BALL MARKING DIE Filed Sept. 9, 1947 Jesse 0. (ya/Z Patented July 15, 1952 UNITED STATES PATENT OFFICE f' 1 I 7 2,603,146 v 1 b I GOLF BALL MARI NG pm Jesse B. Lyon, Cincinnati, Ohio 7 I lipplication'september 9,1194 7, Serial Nofiiiiflzil 1 I. The present invention relates to improvements in marking dies for golf ball marking machines and is particularly directed to a golf ball mark- "ing ,diefhaving novel type characters, which cooperateswith the ball. marking machine to produce clear out and clean indicia in the ball surface that retain the original printing ink for longer periods of time than do ball markings now made. v

An object of the-invention is to provide a type face fora golf ball marking die having a single series of sharp, parallel ridges or. projections which when inked and pressed into the cover of a golf ball produce therein a reverse mark characterized by narrow and relatively deep ink retaining grooves.

Another object of the invention is to provide a novel die construction wherein each character thereon. has an ink carrying face consistingof a series of comparatively deep, closely spaced, s parallel depressions and alternate elevations or .a die having character faces thereon which form in an impressionable golf ball cover a row of clearer and longer lasting impressions and which requires 'a less distorting pressure on the ball during -the impression making operation;

vOther objects will be apparent from the followingsp'ecification and drawings which illustrate the preferred embodiment of my invention, it being understood that certain modifications may be made therein without departing from the spirit and scope of the invention set forth in the appended claim. I

In the drawings wherein like reference numerals indicate similar parts:

Fig. 1 is a perspective view of my golf ball marking die.

Fig. 2 is an enlarged perspective view of a type used in the die illustrated in Fig. 1.

Fig. 3 is an enlarged plan view of a section of a golf ball cover showing the individual mark made by the die illustrated in Fig. 2.

Fig. 4 is an enlarged cross section taken on line 4-4 of Fig. 3.

Fig. 5 is an elevational view of a golf ball marked in accordance with my invention.

1 Claim. (Cl. 101- 303) Fig. 6 is aside elevation of: a golf ball marking machine depicting a manner in .which' the characters of my die are pressed into thesurface of a golf ball cover. V

In the drawings which illustrate a preferred embodiment of my invention thereference numeral l8 indicates an arcuate die which has a number of type characters H 'mounted'inza row on its convex'side If. The die.-is'-used to make corresponding and complementary marksr. Hi

intagilo in the exterior impressionable surface of 2! of the slot is opened so that the desired'numthe last type entered therein. a 4

her and kind of typemay be slid into the slot,

said row'being held therein by forming adepression 2| in the flange adjacent the blankof acter of the type, said type has araised face'22 which-lies in, an offsetplaneparallel to the outside or exposedsurface 23 of the'parallelogram blank. Beard portions 25 taper upwardly from the blank to-the type face ZZ-and intersect, said type face in serrated edges EFL-Fig. .2. ,,Each serrated edge isformed with an alternate series of sharp highpoints 2% and low points 2?; cpposed .low points in the edges being joined; by straight, nonsintersecting grooves ordepressions 28 deeply formed in the type face. As clearly illustrated in Figs. land 2 the grooves are closely spaced and are inclined with respect to the type row in the die and preferably are given an angle of inclination with respect to the longitudinal dimension of the type row approximating 45. Adjacent grooves 28 form between them sharp ridges or elevations 29 which extend between opposed high points 26 formed in the serrated edges 25. In practice I mount a plurality of smooth faced type upon a base plate and then form a series of grooves in said faces by traversing said faces with a milling tool having spaced, V-shaped teeth projecting therefrom. The teeth and the corresponding grooves formed in the type faces are preferably V-shaped for the reason that I have found it most economical and city and state. As illustrated in Figs. 1 and 5 the individuals name set up in the dieerow andethe impression made in a ball cover [3 is 'JiDoe. Cin. 01

Ilascribe these improved qualities oi the type impres- -sion 'to' the fact that the ridges in the atypefface upon impression making'contact -with theiball cover break down the'resistance of the cover material thereby making a: permanent distortion therein and that'said' ridges in the type 'face simultaneously carry ink 'into the distortion "so *formed' Furthermoral had found that golf ball covers .4 printed with dies having conventional smooth face type are subject to lateral deformation during impression making contact with said type due to the local spreading of the elastic ball cover in the area surrounding the type impression, and that the ink on the smooth face consequently is spread outwardly whereby blurred, unequally spaced marks or impressions were made in the ball cover. With my present golf ball marking .die'dess pressure is needed to'make zazclear impression and the sharp ridges in the type faces and sharp high points in the edges provide an effective and simple means for preventing local deformation of the ball cover during impression operations because said ridges sink into the cover and provide traction for the die thereon, so that a. clear -cutimpression is made in the ball cover. The grooves also "retain ink so that it is not spreadfover the area surrounding the typeimpression.
